In an oblique way, Manhunter and The Silence of the Lambs must count as they both feature a cannibal as one of the main characters, with Hannibal definitely counting because of the Ray Liotta brain scene and, of course, the final scene on the plane.

I wouldn't say it's my favourite, but I really liked Meat Grinder, a gory horror film from Thailand in which a woman opens a food store and serves her customers with delicious meat made from anyone who crosses her path.
